Bound approval across channels before long-horizon actions begin

You’re the security / reliability engineer. Your team is in the room. Printed Oct 19, 2026.

Long-horizon service work needs continuity without carrying authority farther than the customer intended.

Cross-channel completion protects the customer from repetition, while bounded approval protects them from an action they did not authorize.

Who you’d be doing this for

“My supervisors keep asking who approved the change after the customer switched from the call to text.”

Kari Larsson · Customer Support Operations Director

Owns service quality and escalation outcomes for an enterprise deploying long-horizon customer agents.

What is at stake

Resumed service actions lack one consistent record of what the customer approved across voice, SMS, and email. You must weigh cross-channel completion against an approval boundary that remains defensible.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • cross-channel continuity vs bounded authority
  • self-serve workflows vs secure defaults
  • customer clarity vs repeated verification
  • launch scope vs reusable trust primitives

Why Sierra

Customer-facing AI agents take actions in connected enterprise systems, so approval must persist safely when service work spans voice, SMS, and email.
